     When one of Ullman's grandsons, Jonas Rosenfield, Jr. was having dinner in Japan a few years ago,

"Youth" came up in conversation, Rosenfield told his dinner companion, a Japanese business leader, that

the author was his grandfather. The news was staggering.

     " 'You are the grandson of Samuel Ullman?' he kept repeating," says Rosenfield, head of the American Film Marketing Association. "He couldn't get over it."

     Then the executive pulled a copy of "Youth" from his pocket and told Rosenfield, "I carry it with me

always."

     Three years ago, several hundred top businessmen and government leaders gathered in Tokyo and

Osaka to celebrate their admiration of Ullman's "Youth". Konosuke Matsushita, founder of the Panasonic Company, said "Youth" has been his motto for 20 years."

     Someone asked, "Why don't Americans love "Youth" as much as we do? It sends a message about

how to live beautifully to men and women, old and young alike."

     Samuel Ullman was born in 1840 in Germany and came to this country as a boy. He fought in the

civil War and settled in Birmingham, Ala. He was a hardware businessman with a liking for public service

that continues 67 years after his death. In the last few years more than $36,000 from Japanese royalties (皇室) on a book and a cassette reading of his work has gone to a University of Alabama at Birmingham

scholarship fund. Not bad for a man who started writing in his 70s.

阅读下面短文,完成下面3个小题

  科学家在地面实验室的实验表明,一些小分子物质经紫外线的照射可以生成氨基酸。光谱分析表明,星际空间存在着这样的小分子物质。科学家还利用卫星进行了有关实验,这样的小分子物质在太阳紫外线照射下生成了氨基酸大分子。因此,一些科学家认为彗星在空间运行时会吸附上这些大分子;而且,由于彗星结构松散,其吸附的大分子在紫外线的照射下更容易产生类生命物质。它们虽有类似原始生命的结构,但不能自我复制。

  据此,有的科学家推测;地球生命之源可能来自40亿年前坠入地球海洋的一颗或数颗彗星。当时地球大气密度很高,减慢了彗星下坠的速度,使彗星表面的温度不会过高,从而保护了彗核表面的类生命的物质。当彗核坠入海洋后,它们得到了再发展的条件,便形成了更为复杂的系统(通常由上百个分子组成)。该系统只让氧气、水等小分子进出,而氨基酸等则不能进出,久而久之这种有序状态促成了该系统能自我复制,进而导致了生命的诞生。

文中所说“更为复杂的系统”最重要的功能是()。

A.能贮存氧气、水和氨基酸等重要物质

B.能让氧气、水等小分子进来,不让氨基酸等出去

C.能自我复制其中类似原始生命的结构

D.能使上百个类生命的分子聚合在一起并长期存在
